Fields and streamers in water with near electrode conductive layers

Deionized water is the most suitable media for pulse storage systems due to high dielectric permittivity, high pulse electric strength, non-toxicity and non-flammability. Here it is attempt to study prebreakdown processes in case of conductive layers near electrodes. The results of experimental studies of the electric field strength distribution in the gap with modified electrodes in water is presented. Pulse electric strength is increased, nonelectrode and postbreakdown streamers are registered. The nonelectrode streamers develop in the form of cathode and anode semistreamers initiated at the same point.
